What Are Over Spanned Floor Joists? 

Over spanned floor joists are a situation where the joists—horizontal supports for your main floor—are set too far apart or lack the strength to support the floor’s load properly. This undermines your floor’s stability. Signs that your home has over spanned floor joists include: 

Ensuring your joists are installed properly is key to a level, solid floor that will sustain any weight or movement inside your home. Staying on top of this issue is vital to prevent more extensive damage and keep your home stable. 

What Causes Over Spanned Floor Joists?

Floor joists are susceptible to damage because of their location under your home. For that reason, some of the causes may go unseen. 

It’s beneficial to be aware of what may cause crawl space damage. Here’s what to keep an eye out for: 

  • Moisture: Humidity in the crawl space causes joists to warp and floors to sag. 
  • Pest Infestation: Termites and other pests can compromise the strength of the joists. 
  • Foundation Troubles: Issues with the foundation can distribute stress unevenly across joists. 
  • Poor Construction: Joists may have been overly spaced apart from the start, creating insufficient support. 
  • Aging: Over time, the floor and joists may weaken without proper reinforcement. 

To safeguard your home’s structure, it’s crucial to identify and resolve these underlying causes quickly. Regular check-ups and upkeep can catch issues early, preventing major headaches and expense.
